A method for delivering media content over a network includes transcoding the media content to generate multiple copies of the media content, each of the multiple copies having a different destination type or a different source type or both, storing the multiple copies in a cache, receiving requests for the media content, and selecting and delivering a copy of one of the multiple copies in response to each of the requests. A further method for providing media content transcoding services includes fetching media content, selecting one of multiple transcoders for transcoding from multiple source types to multiple destination types, wherein the one transcoder is selected based at least on the destination type, sending the media content to the selected transcoder, transcoding the media content to the destination type, thereby generating transcoded media content, and transmitting the transcoded media content.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method for transcoding content from a source type to a destination type, comprising the steps of: fetching content; identifying a destination type; selecting one of a plurality of transcoders for transcoding from a source type to said destination type, wherein said one transcoder is selected based at least on said destination type; transcoding said content to said destination type, therein generating transcoded content; and transmitting said transcoded content.
2. The method of claim 1 , wherein the content is fetched, sent and transcoded as a stream of digital data and said transcoded content is downloaded to a destination of the destination type.
3. The method of claim 1 , wherein said content is fetched, sent and transcoded as a stream of digital data and said transcoded content is transmitted as a stream of digital data.
4. The method of claim 1 , wherein content type is defined according to at least one publishing variable, wherein said at least one publishing variable includes: the file format of the content; the bit-rate of the content; the compression algorithm according to which the content is stored; the communication protocol according to which the content is transferred; or the physical medium on which the content is stored; or combinations thereof; and wherein said step of transcoding comprises converting said at least one publishing variable of the content from a source publishing variable type to a destination publishing variable type.
5. The method of claim 1 , further comprising the steps of: storing said transcoded content in a transcoded cache; and responding to subsequent transcoding requests for the content by fetching said transcoded content from said transcoded cache, and transmitting said transcoded content.
6. The method of claim 5 , further comprising the step of: determining whether to keep said transcoded content in said transcoded cache based on an intelligent algorithm.
7. A method for transcoding content from a source type to a destination type, comprising the steps of: receiving a request for content from a receiver; fetching said content; identifying a destination type corresponding to said receiver; selecting one of a plurality of transcoders for transcoding from a source type to said destination type, wherein said one transcoder is selected based at least on said destination type; transcoding said content to said destination type, therein generating transcoded content; and transmitting said transcoded content to said receiver.
8. A content transcoding device for transcoding content from a source type to a destination type, comprising: a fetching unit for fetching content; an identifying unit for identifying a destination type; a selecting unit for selecting one of a plurality of transcoders for transcoding from a source type to said destination type; wherein said one transcoder is selected based at least on said destination type; a transcoding unit for transcoding said content to said destination type, therein generating transcoded content; and a transmitting unit for transmitting said transcoded content.
9. A computer readable medium having a computer program for causing a computer to perform a method for transcoding content from a source type to a destination type, the method comprising the steps of: fetching content; identifying a destination type; selecting one of a plurality of transcoders for transcoding from a source type to said destination type, wherein said one transcoder is selected based at least on said destination type; transcoding said content to said destination type, therein generating transcoded content; and transmitting said transcoded content.
10. A transcoding device for transcoding content from a source type to a destination type, comprising: a receiving unit configured to receive a request for content from a receiver; a fetching unit configured to fetch said content; an identifying unit configured to identify a destination type corresponding to said receiver; a selecting unit configured to select one of a plurality of transcoders for transcoding from a source type to said destination type, wherein said one transcoder is selected based at least on said destination type; a transcoding unit configured to transcode said content to said destination type, therein generating transcoded content; and a transmitting unit configured to transmit said transcoded content to said receiver.
11. The transcoding device of claim 10 , wherein the content is fetched, sent and transcoded as a stream of digital data and said transcoded content is downloaded to a destination of the destination type.
12. The transcoding device of claim 10 , wherein said content is fetched, sent and transcoded as a stream of digital data and said transcoded content is transmitted as a stream of digital data.
13. The transcoding device of claim 10 , wherein content type is defined according to at least one publishing variable, wherein said at least one publishing variable includes: the file format of the content; the bit-rate of the content; the compression algorithm according to which the content is stored; the communication protocol according to which the content is transferred; or the physical medium on which the content is stored; or combinations thereof; and wherein said transcoding unit comprises a converting unit configured to convert said at least one publishing variable of the content from a source publishing variable type to a destination publishing variable type.
14. The transcoding device of claim 10 , further comprising: a store configured to store said transcoded content in a transcoded cache; and wherein said transmitting unit is configured to respond to subsequent transcoding requests for the content by fetching said transcoded content from said transcoded cache, and transmit said fetched transcoded content.
15. The transcoding device of claim 14 , further comprising a determining unit configured to determine whether to keep said transcoded content in said transcoded cache based on an intelligent algorithm.
